I am trying to power a microcontroller and LED strip off of ONE BATTERY. The LED strip needs a clean 5 V and may use close to an amp, but never actually 1 Amp. I have found some batteries for RC purposes that are 4.8 volts and I think would work for the strip, but the Micro needs more than that to run clean.

I would ideally like to replace the battery as needed, a connector on the micro could make for quick battery replacement.

If I put 4.8 to the Micro will it run correctly?

If I put 6 V or higher to the Micro, are there pins on the Micro that will deliver a clean 5 volts out, able to handle close to 1 amp?

It seems the Teensy is another option, but Im just more familiar with the Arduino environment.Thanks for any insight.
